The lung study found that the lungs of some talc workers in 1975 had been affected. This was probably due to breathing dust produced while mining and milling talc, as well as by smoking. In the breathing tests, we found signs that workers' lungs weren't working as well as expected, even after taking the effects of smoking into consideration.
